Need a little help with p0300
Thanks for the reply. I have been thinking of upgrading to some sort of scan tool instead of my code reader. In one of your earlier posts was a link to a scan tool, I can't find it anymore. Is there any one type you recommend?( not a big fan of my innova's repair solutions). Thanks again- cpt7868
